To all 'whom it may Concern.' p

Be it known that l, CARL Jol-1N HAGs'rRoM, a citizen of the United States, residing at Glen Cove, Long Island, in the county of Nassauand State of New York, have invented certain new and useful Improvements in Locking Mechanism for .Double Doors and Windows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains te make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

The present invention has reference, generally, to improvements in locking mechanism for doors, windows and similar places; and the invention relates, more particularly, to an improvedr construction of combination latch and lock-mechanism for doors, French Casement windows.

The said invention has for its principal object to provide a novel, simple and etlicient construction of .combined lock and latch mechanism operating at three points of the door or Casement window, viz. at the top, bottom, and stile of the door or casement, the three bolts or latches operating to hold the door or easement window at the said three points, being simultaneously controlled by the operation of a single handle or knob. By thus holding the doors or casement windows at the said three points in closed relation to the frame, the same are prevented from warping, and are securely and firmly held in closed position.

Another object of the present invention is to provide a key-lock controlled means for coupling or uncoupling the operative relation of the outside handle or knob devices with the latch-mechanisms, whereby when said handle or knob device is unconpled, the spring-latches cannot be with-1 clearly evident from the following detailed description of the said invention. With the various objects of the present invention in View, the same consists, primarily, in the novel construction of combination lock and latch-mechanism hereinafter set forth; and, the invention consists furthermore, in the novel arrangements and combinations of the various devices and parts, as well as in the details of the construction of the same, all of which will be hereinafter more fully described, and then Jnally embodied in the clauses of the claim which are appended to and which form an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure l is a face view of a French caseient window with the ineeting-stiles thereof shown in section to illustrate embedded therein the novel construction of combined latch and lock-mechanism made according to and embodying the principles of the present invention. Fig. 2a is a detail vertical section taken on line 2a a in said Fig. 2. Fig. 2 is a detail View, enlarged, of said novel combined latch and lock mechanism with the casings o-pen to show the interior construction of operating mechanism, the part being shown in normal or latching position; and Fig. 3 is a similar view, except that the parts are shown in operated.. or unlatching position. Fig. 4 is a detail longitudinal section taken on line 4 4 in said Fig. 2, looking in the direction of the arrow m. Fig. 5 is a detail section taken on line 5-5 in said Fig. 4, looking in the direction of the arrow y, and providing a view of the interior combination latch and lock-mechanism, the same illustrating the key-lock controlled mechanism thereof about to actuate the means for uncoupling the outside or knob device from the latch or bolt-mechanism, so as to render said handle or knob device inoperative from the outside of the door; and Fig. 6 is illustrative of said key-lock controlled mechanism after its actuation resulting in said uncoupling operation. Fig. 7 is a detail view of the tumbler actuated by said key-lock controlled mechanism about to be thrown by said key-lock controlled mechanism into operative engagement with the coupling turnbler, said view being a section taken on line 7 7 in said Fig. 4, looking in the direction of the arrow c, and said view corresponding in time of operation to said Fig. 5; and Fig. 8 is a similar View corresponding in time of operation to said Fig. 6. Fig. 9 is a detail section taken on line 9-9 in said Fig. 4, and illustrating a springcontrolled means for returning the handle and knob mechanism to normal'position after operation. ig. 10 is a detail section through the casing taken on line 10-10 in said Fig. 2, and illustrating in elevation the coupling means connected with said handle or knob members and the coupling tumbler in operative relation thereto. n

Similar characters of reference are employed in all of the hereinafter described views, to indicate corresponding parts.

Referring now to the said drawings, the reference-characters 1 and 2 indicate the respective members of a French casement window which are hinged by their outer stiles to the vertical members 3. of the easement frames. The novel combined latch and lockmechanism made according to and embodying the principles of the present invention is illustrated in said Fig. 1 of the drawings as embedded in the respective meeting styles 4 and 5 of said easement members 1 and 2. The mechanism connected with said meeting stile 4 of the easement member 1 comprises a lock-casing 6, provided with a longitudinal end-plate 7 having an opening 8. This endplate 7 is exposed flush with the meeting surface or edge of said meeting stile 4. Movably arranged within the interior of said lock-casing 6 is a latch-member 9, the operative chamfered end 10 of which projects, normally, through said opening 8 in said end-plate 7. Arranged between the inner end of said latch-member 9, and one wall of said lock-casing 6, are spring-members 11 .which maintain said latch-member 9 in its normally outwardly thrust or projecting positiOn.

Rotat-ably mounted in a suitably disposed opening in one side wall of said lock-casing 6 is a hub or barrel 12 from which extends an annular rib or projection 13, a portion of which is cut away to provide a receiving socket 14. Said hub or barrel 12 is provided with an aXially disposed opening 15, preferably of rectangular cross section. Rotatably mounted in a suitably disposed opening in the opposite side wall of said lock-casing 6 is another hub or barrel 16, the same registering in alinement end to end with said first-mentioned hub or barrel 12, the inner end of said hub or barrel 16 projecting into a receiving portion in the inner end of said hub or barrel 12, so as to be journaled there` in, and so as to maintain the respective hubs or barrels in their registered and alined rela tion one to the other, but each being capable of rotation independently of the other. Extending laterally from said hub or barrel 16 is a lug or tongue 17 and said hub or barrel 16 is further provided with an axially disposed opening A, preferably of rectangular cross section.

The refcrence-character 1S indicates a handle or knob which is journaled in a bearing-plate 19 secured to the inner side of the said meeting stile 4. Connected with said handle or knob 16 is a shank-member 20, one end of which is adapted to be received in said axial opening 15 of said hub or barrel 12, so that when said handle or knob 1S is turned said hub or barrel 12 is likewise rotated therewith. The reference-character 21 indicates a handle or knob which is journaled in a bearing-plate 22 secured to the outer side of the said meeting stile 4. Connected wit-h said handle or knob 21 is a shank-member 23, one end of which is adapted to be received in said axial opening A of said hub or barrel 16, so that when said handle or knob 21 is turned said hub or barrel 16 is likewise rotated therewith. rlhe respective inner ends of said respective shank-members 2O and are joined together by a screw-shank and screw-socket connection 24, whereby the said shanks are capable of independent rotation to actuate the respective hubs or barrels with which they are connected, but owing to such connection cannot be pulled apart axially, to permit the withdrawal of either of said handle or knobs 18 or 21 from their operative assembled relation to said hubs or barrels and said meeting-stile 4 as above described.

Suitably located adjacent to the upper end of the inner longitudinal end wall of said lock-casing 6 is a socket member 25 in which is fulcrumed one end of a coupling tumbler 26, said socket-member 25 being so formed as to permit a longitudinal downward movement of said coupling tumbler 26 as well as a forward swinging movement of the same. rllhe said coupling tumbler is cut away at its free end at 27 to permit the same to straddle said lug or tongue 17 of said hub or barrel 16, so that the couplingpin or project-ion 28 at the extreme end of said coupling tumbler will lie, normally, between said lug or tongue 17 and the end of said annular rib or projection 13 of said hub or barrel 12, so as to be engaged by said lug or tongue 17 when said hub or barrel 16 is rotated, and t-hus transmit the movement of the latter to said hub or barrel 12 by forcing the end of said tumbler 26 against the end of said rib or projection 13. A springmember 29 is connected with said coupling tumbler 26 so as to maintain said coupling-pin or projection 2S in operative relation with said hubs or barrels 12 and 16 in the manner above described. 1When the coupling tumbler 26 is thus normally arranged, by turning the outside handle or knob 21 the barrel or hub 16 is rotated which carries said lug or tongue 17, which forms a part thereof, into engagement with said couplingpin or projection 28 forcing the latter into engagement with the end of said annular rib or projection 13, so that as the barrel or hub 16 rotates its lug or tongue 17 presses against said coupling-pin or projection 28 carrying the same downward, and thus causing a downward movement of said couplingtumbler 26, the upper end of which slides in the receiving-socket 25, as shown in Fig. 3 of the drawings. This downward movement of the coupling-tumbler 26 permits the coupling-pin or projection 28 to press against said annular rib or projection 13 of the hub or barrel 12 thereby causing the latter to rotate, said coupling-pin or projection 28 being maintained in engagement with said annular rib or projection 13 of the hub or barrel 12 by reason of the spring action of said spring-member 29, which causes an outward swinging of said coupling-tumbler 26 simultaneously with its downward movement, and in this manner the rotary movement of said handle or knob 21 and hub or barrel 16 is transmitted to the hub or barrel 12, which by its rotation causes the actuation of the catch-mechanism coupled therewith.

Connected with, and extending laterally from, said hub or barrel 12 is a cam-arm 30, the free end of which engages operatively a tail-projection 31 which extends downwardly from one side of the inner end of said latch-member 9, so that when said hub or barrel 12 is rotated the cam-arm 30 moves against said tail-projection and withdraws inwardly said latch-member 9 from its normal position, and against the tension of the spring 11. As an aid in returning said hub or barrel 12 and said cam-arm 30 to its normal init-ial position, after actuation, there is provided a spring-member 32, one end of which is anchored to a wall of said lockcasing 6, and the free end of which operatively engages said hub or barrel 12.

Pivotally mounted upon a fulcrum-post 33, connected with one side wall of said lockcasing 6, is a lever-member 34. Pivotally connected with one end of said lever-member 34 is a connecting-link 35, the opposite end of which is pivotally connected with an outwardly projecting arm 36 which also forms a part of said hub or barrel 12. Also extending outwardly from said opposite or lower end of said connecting-link 35 is a lug or projection 37. Pivotally connected with the free end of said lug or projection 37 is a pull -piece 38, the :tree end of which is notched, as at 39, to receive a correspondingly notched coupler 40, which is connected with a connecting-rod 41. The said connecting-rod 41 extends downwardly through a suitable longitudinal passage provided in said meeting-stile 4.

Countersunk in the lower end of i saidA meeting-stile 4 is a latch-casing 42, thev cover-member 43 of which is provided with an opening 44 through which projects the chamfered nose 45 of the cylindrical body 46 of a latch-member. The inner end 47 of said latch-casing 42 is cylindrical in form to slidably receive said cylindrical body 46, and a coil-spring 48 is arranged between the end of said inner end 47 and' said cylindrical body 46, to normally maintain said latch-member in outwardly projecting position with its nose received in t-he opening of a striking-plate 49 secured to the sill 50 of the easement-frame. Connected with the cylindrical body of said latch-member is a tail-piece 51 provided with an eye-member 52 in which is inserted the connecting-arm 53 of a slide-piece 54, the latter being mounted slidably in a bearing-piece 55- secured in said meeting-stile 4, said bearingpiece 55 having a slot 56 through which said connecting-arm 53 extends. The said connecting-rod 41 is operatively secured to said slide-piece 54. In like manner, pivotally connected with the other end of said levermember 34 is a pull-piece 57, the free end of which is notched, as at 58, to receive a correspondingly notched coupler 59, which is connected with a connecting-rod 60, the latter extending upwardly thro-ugh a suitable longitudinal opening in said meetingstile 4, and connecting with a latch-mechanism 6-1 of the same general construction abo-ve described, as connected with said connect-ing-rod 41. Said latch-mechanism operates in conjunction with a striking-plate 62 secured in the transom 63 of said casement frame.

As will be well understood from an inspection of the drawings, particularly Figs. 2 and 3, when said barrel or hub 12 is rotated and said latch-member 9 is withdrawn from its easement-closing position, as above described, the arm 36 of said hub or barrel 12 simultaneously operates through the above described lever' system and connecting-rods to withdraw the latch-mechanism at the upper and lower ends of the easement window, from their respective holding engagements with said striking-plates 49 and 62, respectively, of the sill 50 and transom 63 of the easement-frame, thus permitting the easement, which by said mechanism is latched at three points, to be opened when the three latches are thus simultaneously released or withdrawn.

1t will be understood from an inspection of the accompanying drawings that, so long as the coupling-pin or projection 28 of the coupling-tumbler 26 remains in normal coupling contact or engagement between the rib or projection 13 and lug or tongue 17 of the respective hubs or barrels 12 and 16, the latch-mechanisms above described may be operated by turning either the inside handle or knob 18, o-r the outside handle or knob 21. But if said coupling-tumbler 26 is withdrawn so as to withdraw said coupling-pin or projection 28, as shown in Fig. 6 of the drawings, then said outside handle 0r knob 21 will rotate said barrel or hub 16 without transmitting said movement to the barrel or -hub 12, and consequently the easement window is locked from the outside, and can only be opened, that is the latch-mechanisms can only be withdrawn, by turning the inside handle or knob 18.

In order to eii'ect the disengagement or `removal of said coupling tumbler 26 from its normal coupling relation to said hubs or barrels 16 and 12, there is provided a keylock controlled mechanism operable by a `vkey from the outerside of said Casement window to actuate the tumbler throwing means, and a lmob-controlled connection operable from the inner side of the easement window for also controlling the tumbler-throwing means. This mechanism is constructed and operates as follows Rotatably mounted, so as to extend through the inner side of said meeting-stile 4, is the shank 64 of a knob 65. Itotatably mounted by its hubportion 66, which is journaled in a suitably disposed opening in the inner side wall of said lock-casing 6, is an oscillating-cam 67, the same being secured to said shank 64 of said knob 65. Said oscillating-cam 67 is provided with a nosing 68 which is engaged by a flat spring 69, in such a manner, that said spring 69 maintains said oscillatingcarn in either of itsthrown or oscillated positions. Extending outwardly from the body of said oscillating cam 67 are properly disposed cam-projections 70 and 70, so positioned with relation to each other as to provide an intervening space 71. Stop-pins 72 and 78 are mounted upon the wall of said lock-casing 6 and are respectively engaged bythe shoulders 74 and 75 formed in said oscillating-cam 67 according into which of its positions the same is thrown. By properly turning the said knob said oscillating-cam 67 is turned or oscillated to carry its cam-projection into contact with said coupling-tumbler 26 thereby swinging the latter backward upon its fulcrum and carrying its coupling-pin 28 away from its operative engagement and association with said respective hubs or barrels 16 and 12. Said oscillating cam-member is retained in this holding relation to said coupling-tumbler 26 by the action of the spring 69 until the same is again turned in the opposite direction, whereupon the coupling tumbler 26 will be released so that it may be returned by its spring-member 29, and thus again carry into operative association with said hubs or barrels 12 and 16 its coupling-pin 28. It will thus be apparent, that by thus actuating said tumbler disengaging means by turning the knob 65 on the inside of the easement window, that the outside handle or knob 21 is rendered inoperative with relation to thelatch mechanisms and means for withdrawing the same, and consequently the latches serve as bolts to lock the easement window against opening from the outside. In order to permit the opening of the casement window from the outside, when in such locked condition, there is provided a keylock mechanism comprising, a lock-body 76 which is mounted so as to extend through the outer side of said meeting stile t and through the outer wall of said lock-casing 6, and to then register in position above said oscillating cam 67. Rotatably mounted in said lock-body 76 is a key-barrel 77, the rotation of which is controlled by a suitable key-member 7S adapted to be inserted therein. Secured to the inner end of said rotatable key-barrel in any suitable manner is a tumbler 79. This tumbler 79 is set to be eccentric in its movement with relation to said oscillating-cam 67 consequently, when said rotatable key-barrel 77 is turned by the key 78 the tumbler 79 passes into said intervening space 71 between the cam-projections 70 and 70, and if the oscillating cam 67 is set so that the cam-projection 70 is in holding engagement with said couplingtumbler 26, said tumbler 79 is turned so as to pass into said intervening space 71 and engage the end of said cam-projection 70 pushing against the same and thereby oscillating said oscillating cam 67 to carry the same around and remove said cam-projection 70 from such holding relation with said coupling tumbler 26. In so doing, the nosing 68 of said oscillating cam 67 is turned past the dead center of the spring-pressure of the spring 69, so that the spring 69 operates to complete the return oscillation of said oscillating cam 67 until the latter engages the stop-pin 72, and said tumbler 79 passes out of said intervening space 71 and away from engagement with said cam-projection 70, to its normal initial position. Il the oscillating cam 67 is out of engagement with said coupling tumbler 26, and it is desired to withdraw said coupling tumbler 26 from coupling relation to said hubs or barrels 12 and 16 by engaging said oscillating-cam 67 therewith, after closing the casement window from the outside, and thus render the outside handle or knob 21 inoperative and the easement window locked, the key 78 is inserted in said lock-body 76 and said key-barrel 67 is turned in the opposite direction. This operation carries said tumbler 79 into said intervening space 71 and into engagement with said cam-projection 70 of said oscillating-cam 67, thus oscillating the latter, and turning said camprojection 70 into holding and removing engagement with said coupling tumbler 26, the nosing 68 of said oscillating-cam 67 being again carried past the dead center of springp-ressure of the spring 69, so that the spring 69 operates to complete the movement of said oscillating-cam 67, and the said tumbler 79 passes out of said intervening space 71, and away from contact with the cam-projection 70, thus passing back to its normal position so that the key-member '78 may be withdrawn.

In order to further assist the said handle or knob 21, and said hub or barrel 16, and parts operated thereby, to return to normal position after actuation the following device is provided: Countersunk in the inner side of said meeting-stile 4 and secured in a stationary position, is a bearing-member 8O provided with a chambered portion 81. Journaled in said bearing-member is a rotatable element 82 having a perforated lug 88 to which is connected one end of a pullspring 84, the other end of the latter being anchored to a transverse pin 85 passing through said chamber 81. Said `rotatable element 82 is provided with an axially disposed opening through which passes the shank 23 of said handle, said opening corresponding to the rectangular cross-section of said shank. Thus, when the handle or knob 2l and shank 23 are turned, the rotatable element 82 is also turned, thereby putting said pull-spring 84 under tension, which, when said handle or Vknob 18 is released, tends to pull or return the latter, by operation upon said rotatable'element- 82 and shank 23, to its normal initial position.

Connected with, and embedded wit-hin said meeting stile 5 of the easement member 2, is a casing 86, provided with a longitudinal end-plate forming a striking-plate 87, and having an opening 88 adapted to receive the nosing of said latch-member 9 of the latchmechanism connected with the meeting-stile 4 of the adjoining easement member 1. This striking-plate 87 is exposed flush with the meeting surface or edge of said meeting stile 5. Rotatably mounted between the side walls of said casing 86 is a hub or barrel 89 from which projects an arm 90. Said hub or barrel 89 is provided with an axially disposed opening 91,' preferably of rectangular cross section, the same being adapted to receive the shank 92 of handles or knobs 9 3, so that by turning the latter said hub or barrel is rotated, if desired the handle or knob 98 may be arranged to project only on the inner side of the casement member 2, and may be eliminated from the outer side thereof. Pivotally mounted upon a fulcruin post 33 connected with one side wall of said casing 86 is a lever-member 84. Pivotally connected with one end of said lever-member 34 is a connecting-link 35, the opposite end of which is pivotally connected with said4 arm 90 of the hub or barrel 89. Also extending outwardly from said opposite or lower end of said connecting-link 35 is a lug or projection 37. Pivotally connected with the free end of said lug or projection 37 is a pull-piece 38, the free end of which is notched, as at 39, to receive a correspondingly notched coupler 40 which is connected with a connecting-rod 4l. The said connecting-rod extends downwardly through a suitable longitudinal passage provided in said meeting-stile 5 and in the lower end of which is a latch-casing 42, the cover-member 43 of which is provided with an opening 44 through which projects the chamfered nosing 45 of the cylindrical body 46 of a latch-member. The inner end 47 of said latch-casing 42 is cylindrical in form to slidab-ly receive said cylindrical body 46, and a coil-spring 48 is arranged between the end ofsaid inner end 47 and said cylindrical body 46 to normally maintain said latchmember in outwardly projecting position with its nosing received inthe opening of said striking-plate 49 secured to the sill 50 of the easement frame. Connected with the cylindrical body of saidA latch-member is a tail-piece 5l provided with an eye-member 52 in which is inserted the connecting arm 53 of a slide-piece 54', the latter being mounted` slidably in a bearing-piece 55 secured in said meeting-stile 5, said bearingpiece 55, having a slot 56 through which said connecting-arm 58 extends. The said connecting-rod 41 is operatively secured to said slide-piece 54. In like manner, pivotally connected with the other end of said lever-member 34 is a pull-piece 57, the free end of which is notched, as at 58, to receive a correspondingly notched 'coupler 59 which is connected with a connecting-rod 60, the latter extending upwardly through a suitable longitudinal opening in said meeting-stile 5, and connecting with a latch- Y mechanism 61 of the same general construction above described as connected with said connecting-rod 41. Said latch-mechanism operating in conjunction with said strikingplate 62 secured in the transom 63 of said casement frame. A spring-member 94 is connected to one end of said lever-member 34 and its other end anchored to some stationary point within said casing 86, the same serving to return the above described parts` to their normal initial position after actuation.

As will be apparent the above described latch-mechanism serves to hold the easement member 2 at the top and bottom thereof in latched engagement with the easement frame, and at the same time provides a striking-plate and latch .receiving portion vfor the latch-member 9 operatively associated with the meeting-stile 4 of the casement member 1. It will also be apparent that by operating the handle or knob 93 both of said latch-mechanisms operated by the interconnecting lever-system may be withdrawn simultaneously from their latched relation to said easement-frame.

From the above description the novel construction of combined latch and lock mechanism and operating means, together with its mode of operation will be readily understood.

I am fully aware that some changes may be made in the arrangements and combinations of the various devices and parts, as well as in the details of the construction of the same, without departing from the scope of the present invention as set forth in the foregoing specification, and as deiined in the claims which are'appended thereto.
